Font rendering on Windows XP shows artifacts with QML Text element

When creating a simple Qml Text example I get rendering artifacts on Windows XP. The example rendes correctly on Windows 7 and osx. I've only been able to test on a single Windows XP machine.

The error, code, and system information is shown in the attached image
The error is visible in the simple example:

 
Text{
 text: "Some text"
 font.pixelSize : 60
}
